Bob's age is 4 times greater than Susanne age. Dakota is three years younger than Susanne. the sum of bobs, Susanne's, and Dakota's ages is 93. what is Susanne's age

Susanne is 16 years old.

Step-by-step explanation:

You're gonna need three equations.

Key: B = Bob, D = Dakota, s = Susanne

B = 4s

D = s - 3

B + D + s = 93

Now plug in B and D into the third equation:

4s + (s - 3) + s = 93

Now solve it:

4s + s - 3 + s = 93

6s - 3 = 93

+3 + 3

6s = 96

6s/6 = 96/6

s = 16
